reconnect! method resets the @servers parameter

[subelsky]

I believe this code in cassandra.rb does not respect the @servers parameter:

def new_client
thrift_client_class.new(CassandraThrift::Cassandra::Client, @servers, @thrift_client_options)
end

It seems to return a client which uses the default localhost value for @servers, which causes this to happen:

irb(main):005:0> cass = Cassandra.new(:OtherInbox,"10.208.130.191:9160")
=> #<Cassandra:77305550, @keyspace=:OtherInbox, @Schema={}, @servers=["10.208.130.191:9160"]>
irb(main):006:0> cass.instance_eval { @servers }
=> ["10.208.130.191:9160"]
irb(main):007:0> cass.get(:MerchantDomains,'example.com')

I am working on a patch but dont' fully understand how the thrift client works; thought I'd post here first in case this is already known to you.

seems like it must be a problem with the thrift client gem and my particular network setup -- I'm not able to reproduce it in a test. grr.

this should probably be merged into issue 10 http://github.com/fauna/cassandra/issues/issue/10/

Ah hah! Found the answer in issue 15; you need to set the ListenAddress properly in the Cassandra server config. Will be submitting a doc patch to help others. http://github.com/fauna/cassandra/issues/closed#issue/15
